About our fire stopping in Whitehawk

Facilities managers in Whitehawk often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. We work on joints between fire-resisting walls and floors, cable penetrations and pipe penetrations, and the usual reasons a site gets in touch are unsealed penetrations discovered above suspended ceilings and improvised or mixed-product fire seals. Most enquiries from Whitehawk start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Buildings in a smaller place such as Whitehawk that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Where services cross fire walls in Whitehawk

The area within 2 miles of Whitehawk holds a good number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

On a hospital site such as The Royal Alexandra Children's Hospital (0.6 miles south-west of Whitehawk), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Workshops and IT rooms at colleges like Waterbear College Brighton, 1.6 miles to the west of Whitehawk, are re-serviced often, leaving penetrations to seal.

Whitehawk is about 1 mile south-east of Brighton, in Brighton and Hove. Any commercial site in Whitehawk is covered, whether it’s a single job or part of a planned programme. Across Brighton and Hove, 29 places are covered, Whitehawk among them.

Commercial sites across BN2 are covered. For a building on Peel Road, Manor Road and Craven Road or nearby, we can quote for service penetrations. Just outside Whitehawk, we also work in Kemptown (1 mile south-west), Hanover (1 mile west), Carlton Hill (1 mile west), Bevendean (1 mile north) and Brighton (1 mile north-west). Bigger towns within reach include Brighton and Hove (4 miles west), Hove (3 miles west), Portslade (5 miles west), Aldrington (4 miles west), Withdean (3 miles north-west) and Hangleton (5 miles north-west).

Around Whitehawk

Locally, jobs take us to sites close to St Mary's Hall, Whitehawk Hill and Longhill High School and the streets around them. For rail, the closest station is Brighton station, roughly 1.6 miles west. Nearby you will also find Brighton Motor Museum (0.7 miles south-west) and Royal Sussex County Hospital (0.6 miles south-west). The countryside around Whitehawk includes Newmarket Hill and Whitehawk Hill.

Why act early in Whitehawk

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Why appoint us

  • Health and safety: CHAS accredited
  • Old sealant cut out, never sealed over
  • Workmanship guaranteed for 12 months
  • A Constructionline member, so easy to vet

Commercial clients in Whitehawk

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

When to call us in Whitehawk

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

If one of these sounds familiar, it’s time for a closer look:

  • Unsealed openings around new pipes and cables
  • Fire-rated sealant that has cracked or shrunk back
  • Head-of-wall gaps with no fire seal
  • Penetration schedules that need working through

At a university such as University of Brighton, which lies north of Whitehawk, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Will RAMS and insurance details be available?
  • Health and safety accreditation such as CHAS
  • How long is the guarantee, and what does it include?

Questions to ask before you appoint anyone

Common questions from Whitehawk clients

Can you take on a job at a hospital such as The Royal Alexandra Children's Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

What does the BS 476 change mean for fire-rated sealant in Whitehawk?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can the building stay open while you work?

Normally, yes. We phase the work so most of the building stays in use.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Reviewing a building’s overall fire safety
  • Deciding what a wall or floor needs, which belongs to the designer
  • Signing off or certifying a building’s fire stopping

If you are not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

What we seal

  • Linear gaps at wall heads
  • Small duct penetrations where the tested detail allows
  • Pipe penetrations
  • Joints between fire-resisting walls and floors
  • Service gaps in risers
  • Cable penetrations

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Work in places the size of Whitehawk is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Flag any permit to work we’ll need
  • Send your site hours and access windows
  • Have the specification and drawings to hand

What the job involves on each surface

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Linear joints

Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, with no gaps along the run.
